Making the city both dense and green is today described as a part of realizing sustainable urban development. Although dense city planning previously has led to less greenery, it is now a development strategy that is used to achieve both aspects. The purpose of this essay is thereby to bring light to the discourse about greenery in the planning process of the dense city. Critical discourse analysi
In this master’s thesis we propose a DensePose-based person re-identification (re-ID) machine learning algorithm building upon previous research on this topic. DensePose, a deep neural network that performs human body part segmentation on images, forms the foundation of our approach. We investigate whether utilization of DensePose can enhance performance on re-ID algorithms with the utilization of
Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter". A significant challenge for LDMX is to efficiently veto rare photo-nuclear back
Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. This thesis consists of two parts regarding in-plane wetting into the paperboard.
Wide-angle distance measurements are needed for positioning with multilateration when there is no information about in which direction objects of interest are located. Several transmitters of varying kinds were evaluated in a data-driven way using a 6 DOF robot actuator. A wide-angle (±98 degrees) distance measurement system us- ing ultrasound was developed. The resulting solution was integrated i
Geographic Information Systems (GIS) are a powerful tool for supporting disaster risk reduction (DRR). International agreements such as the Sendai Framework for Disaster Risk Reduction call on high-income countries and other partners to support lower-income countries in strengthening their DRR capacities. This thesis explores the experiences of stakeholders in strengthening GIS capacities for DRR
Cities around the world are leading the race toward an environmentally sustainable future, but one of their major obstacles have been the personal automobile. The movement of people using public transportation often has a far lower impact than the personal automobile, but these systems are often rigid and expensive to build and operator. Now, with the emergence of intelligent transport systems – a
With rapid urbanization and population growth, Addis Ababa faces a big challenge of dealing with slums in the inner city. It has used up most of its space within its boundary and there are now a number of projects on the pipe line to redevelop the inner city slums. This seems to be the single most pressing issue currently. The recent public housing projects and inner city renewal programs has cau
Felaktiga domar sker i både Sverige och andra stater. Detta trots att straffprocessen innehåller starka krav på rättssäkerhet så som oskyldighetspresumtionen och rätten att inte bli lagförd två gånger för samma sak. Den senare principen hänger ihop med regeln om att när en dom inte längre kan överklagas får den rättskraft, innebärande att fallet inte får prövas igen i ny rättegång. Alla ordinära rWrongful convictions happen both in Sweden and other countries, even though the criminal justice system is filled with principles regarding the rule of law, such as the presumption of innocence and the right not to be tried or punished twice. The latter is closely linked with the general rule that once a verdict no longer can be appealed, it enjoys legal force (prejudice), meaning the case cannot
I följande uppsats kommer jag att undersöka rättsprincipen negotiorum gestio. Principen stadgar rätten till ersättning vid ingripande för annans intresse vid den personens frånvaro. Den hjälpande kallas gestor och den som åtnjuter tjänsten huvudman. Rättsinstitutet har historia tillbaka till det romerska riket och har sedan dess levt kvar rättsbildningen. I Sverige har aldrig någon kodifikation avThe following essay investigates the principle of negotiorum gestio – also known as benevolent intervention. The core actors of the principle are the helper called gestor and the helped called dominus. The principle regulates reimbursements to the gestor when managing dominus business in their absence. The principles emerged in the ancient roman empire due to its massive expansion and is still rec
This thesis aims to explore the problems archaeologists have to face when working with mixed kontexts and multi cultural technologies. The thesis explores how archaeologists could use linguistic explanations when working with material culture studies and how material culture spreads in human societies. The thesis concludes that material culture spreads and function like language and that such meta
The purpose of this study is to investigate how pictures of good parenting is challenged, consolidated and renegotiated on a Swedish online-community for parents. This online-community includes a forum feature consisting of several categories, whereas data for this study were collected from the category “childrearing”. With a qualitative approach, a netnographic document study was used to obtain e
Bakgrund: Många barn känner obehag och rädsla inför medicinska åtgärder inom sjukvården. Studier har visat att nålrelaterade moment är det som upplevs mest skrämmande. Barn kommer till en röntgenavdelning för att undersökas och ofta behöver kontrastmedel injiceras. Stickrädsla hos barn är ett vanligt förekommande problem och det är därför viktigt att åtgärda det. Syfte: Studiens syfte var att unde
The phase center is defined as the point on an antenna from which the far field radiation seems to originate. Phase center calculations are often uncertain and vague, and very little concrete information is available on the subject. Recently, a replacement parameter called the radiation center was introduced in [5]. The radiation center is more rigorously defined than the phase center and possesses a
Purpose: The purpose of this study is to investigate whether certain CEO- and firm characteristics have an impact on the extent of abnormal return on Swedish firms at the event of a CEO insider trade. Furthermore, the study aims to examine whether there is a difference depending on firm size and sector. Methodology: An event study has been performed based on the market model where the presence of

Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack. Coniferous forests are known to produce larger quantities of BVOCs, especially terpenes,
The aim of this thesis is to identify a speaker in a video stream by only using the camera of a smartphone. This creates the opportunity for a mobile application to track the speaking participant during a conference call. Conference systems that include this feature use a microphone array to localize sound and who the speaker is. Mobile phones however, are generally not equipped with a microphone
En stor del av samhällets miljöpåverkan kommer från bygg- och fastighetssektorn. Från årsskiftet 2022 finns det nya krav för nybyggnationer på att en klimatdeklaration ska genomföras för bärande konstruktionsdelar, innerväggar samt klimatskärmar. Kraven kan vara ett startskott för att fler delar i byggnader ska klimatdeklareras. Projekt Villazero, ett småhus som uppförs i Borlänge av Fiskarhedenvi
This thesis was dedicated to investigating the use of different parameter update schemes for Hidden Markov models with time-varying parameters, with an emphasis on developing alternatives to the quasi-Newton step. The focus was on applications to financial returns, using data from the S\&P-500 and the Nikkei index, and for comparison, a trial using synthetic data was also performed. Different
